Barbula indica Sprengel ex Steudel 1824

Sporophytes of Barbula indica are rare in the flora area (collection date of the single fruiting collection seen not given). The distal laminal margins are usually plane and the abaxial surface of the costa is prorate, i.e., papillose by projecting ends of cell walls, often forming doubled projections, but sometimes additionally papillose by simple or 2-fid papillae.

Stems to 1.2 cm. Leaves firm when wet, long-ovate to ligulate, 0.5-1.8(-2) mm, base often elliptic, widened not strongly sheathing, margins plane or weakly recurved to mid leaf, apex broadly acute to rounded, apiculate or occasionally muticous; costa percurrent or ending 1-4 cells before the apex, abaxial costal surface doubly prorate (rough by projections at each end of superficial cells), often also with simple or 2-fid papillae, hydroids absent; distal laminal cells firm-walled, quadrate, 7-10 µm wide, 1:1, papillose. Specialized asexual reproduction by gemmae borne on stalks in leaf axils. Perichaetial leaves obtuse to broadly acute, strongly sheathing and convolute. Seta 1-1.8 cm. Theca 0.8-1.2 mm. Spores 10-12 µm.

Plants small to medium-sized, 5–17(–25) mm high, yellowish green to dark green, in loose or dense tufts. Stems erect, simple or irregularly branched, often radiculose at base; central strand well differentiated. Leaves contorted when dry, erect-spreading when moist, ovate-lanceolate to narrowly ligulate, 1.1–1.6 mm × 0.3–0.5 mm, rounded obtuse at apex; margins entire, plane; costa stout, percurrent or shortly excurrent, coarsely papillose on dorsal surface; upper leaf cells small, usually rounded-quadrate to hexagonal, 10–16 µm × 8–14 µm, rather thin-walled, obscure, multi-papillose or mammillose; basal cells differentiated, rectangular, 16–44 µm × 6–12 µm, smooth, hyaline. Gemmae present in leaf axils. Dioicous. Setae 5–10 mm long; capsules erect, oblong-ovoid to cylindrical; peristome teeth linear, erect, densely papillose; opercula conic -rostrate, with a long, oblique beak.

Distribution: China, Japan, India, Indonesia, and the Philippines.

Habitat: on rocks, forest ground, or on soil walls.
